Knowledge

Children become experts: Topas explains the world of aerosols

Our enthusiasm belongs to aerosols and everything that has to do with it. We told the pupils of a Dresden primary school about our passion. In four exciting research lessons, the enthusiasm for aerosols was quite noticeable in the classroom. What exactly is an aerosol? What shapes and sizes can be found? And in accordance with the current situation: How many viruses on top of each other add up to a Lego man? The children of class 2b approached these captivating questions playfully: with the help of the overhead projector, dust became visible in the classroom. Exciting experiments with the particle counter, various fabric samples and the much sought-after fog generator visualised the effects of masks and proper ventilation. And in the school playground, the children themselves became particles. In the end, everyone agreed: Aerosols are part of our lives - they just must not become too much. And when dangerous viruses are involved, proper ventilation and the right face mask can help. We couldn't have imagined better praise than Merten's sentence at the end of the research class: "That was the craziest lesson for a long time!” Same for us, Merten!
